Bank Identifier Code

What is Bank Identifier Code?

Bank Identifier Code (BIC) is a standardized 8- or 11-character code that uniquely identifies a bank or financial institution in international transactions. Defined by the ISO 9362 standard, it tells payment systems which institution, and optionally which branch, should send or receive a cross-border transfer.
A BIC is also known as a SWIFT code, because it's the address banks use to route messages across the . Every code resolves to a single institution worldwide, so automated systems can direct funds to the correct recipient without depending on a bank's name or postal address. Cross-border wires and interbank messages rely on the BIC to reach the right institution. Banks, payment processors, and corporate treasuries look up a counterparty's BIC before sending a wire so the instruction carries an unambiguous destination.

Key facts

  • Also known as: SWIFT code.
  • Standard: ISO 9362.
  • Length: 8 characters (head office) or 11 characters (specific branch).
  • Managed by: SWIFT, the ISO 9362 registration authority.
  • Used for: routing cross-border transfers and interbank messages.
Every BIC follows the same layout regardless of length. The code reads left to right and breaks into four parts:
  • Bank code – four letters identifying the financial institution.
  • Country code – two letters based on the ISO 3166-1 country standard.
  • Location code – two letters or digits for the institution's city or head office.
  • Branch code – an optional three characters pointing to a specific branch. An 8-character code omits this and defaults to the head office.

Types of BIC

BICs vary by length, which controls how precisely the code points to an institution:
  • BIC8 (8 characters) – identifies a bank's head office and routes to its primary processing location.
  • BIC11 (11 characters) – adds a three-character branch code to direct funds to a specific branch or department.
So an 8-character code addresses the institution as a whole, while the 11-character version isolates one office within it. Length isn't the only distinction. A connected BIC is registered and active on the SWIFT network and can carry live payment messages, while a non-connected BIC exists for reference and identification only. Both forms are valid ISO 9362 codes; only connected BICs can actually move money over SWIFT.

Why it matters

An accurate BIC routes an international transfer to the right institution on the first attempt. When the code is wrong or missing, the payment either lands at the wrong bank or stalls in manual repair, and each detour adds processing days and recovery fees before the money reaches the beneficiary. For high-value or time-sensitive payments, that delay carries real cost.
BICs also anchor compliance checks. Banks screen the sending and receiving institutions against and sanctions lists, and a verified institutional identifier makes that screening reliable while helping flag before settlement. The same identification underpins correspondent banking, where one bank holds accounts for another to clear payments in currencies or regions it can't reach directly.

How it compares

A BIC identifies the bank that holds or moves the money; other identifiers in a transfer point to the account itself or to a card's issuer. The difference matters because "bank identification code" and "bank identification number" sound alike and get used interchangeably, even though one routes interbank transfers and the other sits on a payment card.
